Retry attempts 344/infinite. Message: Error trying to extract package at path /etc/packages/com.myapp/myapp-base.ui.content-5.1.0-SNAPSHOT.zip

Cause

The sling-distribution-importer user needs additional permissions per the content paths defined in the ui.content package. This usually means we need to add permissions for both /conf and /var.

Solution

The solution to this is to add a RepositoryInitializer OSGi configuration script to your apps deployment package to add ACLs for the sling-distribution-importer user.
In the example error above, the package myapp-base.ui.content-*.zip includes content under /conf and /var/workflow. In order for the deployment to not fail, we would need to add permissions for sling-distribution-importer under those paths.

Here's an example [1] of one such OSGi configuration that adds additional permissions for the sling-distribution-importer user. This configuration adds permissions under /var. This xml file below [1] needs to be added to the application package under /apps/myapp/config (where myapp is the folder where your application code is stored).
